    Question

    Suppose a triangle with the vertices A (–2, 4), B (–1, –3), and C (4, –2) were dilated, with the centre of dilation at the origin and with a scale factor of 2. The coordinates of C' is ?

    1. (2, -1)
    2. (8, -4)
    3. (8, 4)
    4. (2, 1)

    hintHint:

    The scale factor is a measure for similar figures, who look the same but have different scales or measures. for the dilated to scale factor of the coordinate we should multiply the scale factor

    The correct answer is: (8, -4)

      A triangle with the vertices A (–2, 4), B (–1, –3), and C (4, –2).
      Dilated, with the centre of dilation at the origin and with a scale factor of 2.
      The coordinates of C' is (4 x 2, -2 x 2) = (8, -4)
